Saving heat saves money, tips on how to stay warm more cheaply


DENVER (KDVR) – Colorado electricity and natural gas prices are at record highs. Reducing energy consumption through inexpensive or free measures can help reduce costs by 20 to 30%, according to the Colorado State University Extension.

Do-it-yourself ideas from CSU Extension that can be used for homeowners and renters:

Windows, doors and sealing

  • Check for leaks around the windows
    • Clean tracks for a good seal
    • Lock window for better sealing
    • Seal external doors and windows as required and apply sealing strips
  • Use a door sweep to reduce air leaks under exterior doors
  • Seal and seal leaks when pipes, conduits, or electrical lines penetrate through exterior walls, floors, and ceilings
  • Install foam gaskets behind electrical outlets and switch panels on exterior walls
  • Open blinds and blinds on sunny winter days and close them at night
  • Install storm windows over toughened windows or use plastic film window kits

HVAC – heating, ventilation and air conditioning

  • Set your thermostat as low as comfortable (68 F is recommended) when you are at home
  • Set the thermostat back to 60 F at night or when no one is home
  • Reset the thermostat to 50-55 F if the house is empty for more than 24 hours
  • Install a programmable thermostat to automatically provide these setbacks
  • Operate the system on the fan setting “auto” on the thermostat
  • Have your oven checked annually by a trained specialist
  • Replace the oven filters once a month during the heating season

Attics, basements and crawl spaces

  • Check all visible channels
  • Look for holes leading from a heated room into a basement or attic that needed sealant or foam
  • Seal all joints in ducts with duct putty
  • Make sure the heating registers are not blocked or closed (as closed registers put pressure on the ducts and can make them leak)
  • Isolating ducts that run through unheated rooms

Water heaters and leaking taps

  • Turn the temperature setting to 120 F. down
  • Repair leaky faucets, hot water taps are expensive


  • Disconnect, drain and store all garden hoses
  • Exposed water pipes in uninsulated rooms such as crawl spaces, attics or outside walls should be protected with foam insulating sleeves to prevent burst pipes


  • Upgrade recessed socket lights to ones that are designed for insulation contact and airtightness
  • Upgrade attic insulation to R-49 or higher (higher R values ​​mean higher insulation values ​​and thus more energy savings)
  • Insulate the heated outer cellar walls to at least R-11
  • Insulate floors over unheated areas on R-19

Wood-burning fireplaces

  • Close your chimney flap, seal the opening when the chimney is not in use
  • Use a chimney balloon to close air leaks in under-used or inactive chimneys

Colorado Low-Income Energy Assistance Program benefits can include repairs or replacements of a home’s primary heating system and weather services. Information on the application process, eligibility and the LEAP program is available online.

Arapahoe County’s Weatherization Division is installing many of these energy saving measures at no charge to eligible homeowners and renters.
